Abstract (en)
[origin: US5958528A] The invention relates to a data carrier, such as an identity card, credit card or the like, with at least one plastic layer having first diffusely light-scattering properties at least in a partial area due to its surface quality. In this area information is provided by means of a laser in the form of local changes of surface quality which have second diffusely light-scattering properties so that the information is readable at least at a certain viewing angle but has no color contrast with its surroundings.
